Metastable supersymmetry breaking and multitrace deformations of SQCD
Rouven Essig, Jean-Francois Fortin, Kuver Sinha +2
Metastable vacua in supersymmetric QCD in the presence of single and multitrace deformations of the superpotential are explored, with the aim of obtaining an acceptable phenomenolo…
Comment on: "The Casimir force on a piston in the spacetime with extra compactified dimensions" [Phys. Lett. B 668 (2008) 72]
S. A. Fulling, K. Kirsten
We offer a clarification of the significance of the indicated paper of H. Cheng. Cheng's conclusions about the attractive nature of Casimir forces between parallel plates are valid…
AdS Wormholes
A. Bergman, H. Lu, Jianwei Mei +1
We obtain a large class of smooth Lorentzian p-brane wormholes in supergravities in various dimensions. They connect two asymptotically flat spacetimes. In cases where there is no…
Yukawa Corrections from Four-Point Functions in Intersecting D6-Brane Models
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We discuss corrections to the Yukawa matrices of the Standard Model (SM) fermions in intersecting D-brane models due to four-point interactions. Recently, an intersecting D-brane m…
The Superconformal Gaugings in Three Dimensions
Eric A. Bergshoeff, Olaf Hohm, Diederik Roest +2
We show how three-dimensional superconformal theories for any number N <= 8 of supersymmetries can be obtained by taking a conformal limit of the corresponding three-dimensional ga…
Tachyon Mediated Non-Gaussianity
Bhaskar Dutta, Jason Kumar, Louis Leblond
We describe a general scenario where primordial non-Gaussian curvature perturbations are generated in models with extra scalar fields. The extra scalars communicate to the inflaton…
